HOLDER FOR PENCILS.

SPECIFICATION forming part of Letters Patent No. 364,303, dated June 7,1887,

Application lled March 15, 1886. Serial No,195,334. (No model) Patentedin Germany November 1D, 1885. No. 35,867, and Novemlmr21.1885,No.36,478;in England December l?, 1885, No, 15,533, and in Austria-Hungary July52, 1F86.

To all whom it may concern:

Be it known that I, MORITZ SACHS, a subi ject of the King of Bavaria,residing in Nuremberg, Bavaria, Germany, have invented a new and usefulImprovement in Holders for Pencils and Similar Objects, (for which Ihave obtained patents iu England, No. 15,533, and dated December 17,1885; Germany, No. 35,867, November 19, 1885; patent of additionthereto, No. 36,478, of November 24, 1885, and Austria -Hungary July 2,1886,) of which the following is a specification.

My invention relates to t-he contrivauce for feeding forward,withdrawing, stopping, and releasing the movable core or tube of holdersfor pencils, pens, and other small instruments.

In describing the invention reference will be made to the accompanyingdrawings, of which- Figure 1 is an axial section 0f an improvedpencil-holder, the movable core being withdrawn; and Fig. 2, an axialsection of the same, the movable core projecting. The remaining figuresrepresent. modifications and details.

The outer tube, a, contains the black-lead tube b, fastened at its lowerextremity. The blackdead tube b is furnished with a long slit, b', andtwo lateral recesses, bz. To the tube b is fixed a small tube, c,furnished with elastic cheeks c', which catch into the' recesses b. Thetube b contains the black-lead d, over which lies freely the slide gwith the catch g. The latter projects from the tube slit b' and catchesinto the screw-thread hof the tube h. This tube h is adapted to revolvethe tube Z), and also (as in pencil-holders with so-called Englishguiding to be displaced longitudinally thereon. lt is raised at theprojection h2 by the spiral spring i, resting on the bent portion a ofthe tube, acts in raised position, Fig. l, with its bent lowerextremity, h3, on the clipping-checks c', and project-s with its up perend the tube-head h* from ont of the tube a. By pressing on thetube-head h, Fig. 2, the slide g g is moved longitudinally Within thetube h h', and thereby the blaclolead released from the clipping-cheeksis fed forward. When the pressure on the tube-head h ceases, theblack-lead remains in the forward position, if the holder liehorizontally, while the tube h h', with the slide g g', gets back againintothe original position and clips the blaclolead fast again. By afurther pressure on the head h, while the point' of the holder is heldupward, the lead can be brought into the original position, as inFig. 1. rlhe slide g g' being also adapted to be shifted by turning thetube h h', this slide can, with the varying length of the black-lead,always be put in a position which allows the black-lead to be fedforward in the requisite amount for use by pressing the tube-head 711i.The blacklead, of course, cau also be fed forward for use by Inerelyturning the tube h.

Figs. 3, 4, 5, and G represent likewise a holder with feed mechanism.This device is equal to that of Figs. 1 and 2, with the only exceptionthatin theholder shown by Figs. 3, 4, 5, and G the black-lead d isrigidly connected with the slide g g', and the small tube c with theclippingcheeks c and the tube-recesses b2 are omitted. Owing to theconnection of the black-lead d with the slide g g the black-lead d,if'only the arrangement shown by Figs. 1 and 2 were applied, could bepropelled by longitudinally displacing the tube Il., but could not beretained in its forward position. For attaining the latter purpose astopping and releasing dcviee is arranged, which, as it will be shown,may also be applied to holders with differently-constructed feedmechanism.'

The stopping and releasing device consists,

(Fig. 3,) first, of the elastic catches k, fixed to the tube a; second,of atube, m, secured on the tube It, and provided with an outslandi ngring, m', preferably of an ogival or conical form, adapted to arrivebetween the catches 7c and press the same apart, so as to arrive infront of them; third, of the ring n, sliding ou the neck h5, above thesaid conical part mi', and having an exterior diameter somewhat largerthan the base of the said part m', its travel on the said neck h beinglimited downwardly by the said conical part m' and upwardly by theflange h".

By shifting forward thesleeve h h,and there fore the slide g g'withblack-lead d, by press ure on the head h the ring m' passes between thepoints of the catches k and the latter rest on the neck h, and the baseof the ring m is pressed back onto the said points by the action of thespring i, so that the tube h h', and there ICO fore the black-lead (l,(or pen, crayon, or the like) is held firmly in its forward position.When the black-lead is to be released, the head h* is pressed fartherdownward into the ease, by which means the flange h arrives on the ring`n and forces the latter downward between the points of the springs lr.0n releasing the head h the slide h h', with all the parts lr h m' n, ismoved upward in the case by the spring 'i'. By this means the base ofthe ring m arrives against the ring n, forcing the latter from betweentlie catches k, which slide off onto the sides of the ring m', so as tofree the latter, and the whole mechanism resumes the position shown inFig. 3.

Fig. 6 is a cross-section of Fig. 5 along line A B. As also thisarrangement permits the tube h h' to turn on the tube b b', the slide gg' can also here, when the length of the blacklead changes, be broughtinto a position which allows the black-lead to be shifted forward foruse by pressing the tube-head h. Moreover, here the black-lead can alsobe fed forward as well as withdrawn by merely turning the tube h h. 'Thefeeding forward and withdrawal of the black-lead can here be effected inany position of the holder by pressing as well as by turning.

I do not confine myself to any particular lshape or number of catches,la. Also, I may replace the screwthread pressed into the material of thesleeve h by a helical rail fixed to or formed on the inner surface ofsaid sleeve.

The arrangement of the separate parts of the stopping and releasingdevice may also be different from that shown by Figs. 3, 4, and 5. Figs.7, 8, 9 represent such a modification of a holder, with a part, h,simply adapted to slide longitudinally, which, as in the holdershitherto described, is in connection with a spiral spring, i'. Here thecatches are fixed to the part li and tend to expand or separate fromeach other by their elasticity. The slide-surface m, with the projectionm', however, is situated on the stationary tube a that is to say, theyare formed by this Very tube, and themovable ring n may be displacedwithin the limits m' and h, Fig. 7. The arrangement is here made so thatby displacing the part h (which may carry a pen, o, or a black-lead andsuch like) the catches k, which press against the sliding surface m,slide on the latter until they arrive behind the projection m', wherethey spread so as to abut when the pressure ceases on the saidprojection and be retained thereby, as shown in Fig. 8. When the part liis again fed forward, the catches k are pressed together inwardly, Fig.9, by the ring n, situated at the limit h, and they are held in thisposition by the ring a until the latter is suddenly thrown upward withthe parts k k by the spiral spring i, when the pressure on h* ceases andis stripped off when abutting against the projection m' by the catchesk, which thereby get on the sliding surface.

With holders in which the movable part h is not turned the movable partn need not b e ring shaped. This part may, for instance, if the stoppingdevice is arranged as shown by Figs. 3, 4, and 5, consist of two smallparts of a ring connected by a pin, which partsarc guided and stopped bya pin working 1n a slot of the neck lr" ot' the tube.
